Title:
DIRECT CURRENT UNINTERRUPTIBLE POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/069010
Kind Code:
A1
Abstract:
Disclosed is a direct current uninterruptible power supply system. The direct current uninterruptible power supply system according to an embodiment of the present invention is electrically connected to a direct current power converter for converting commercial alternating current power to direct current power, in order to: supply the direct current power to a load and charge an auxiliary power supply system therein with the direct current power. In the case of a short circuit of the direct current power converter due to a current leakage or breakage of the direct current power converter, or if the direct current power converter is disconnected, the direct current uninterruptible power supply system enables the auxiliary power supply system to constantly supply power to the load while completely blocking the electrical connection to the direct current power converter. In addition, because a CPU and a software controller are not provided, the direct current uninterruptible power supply system can prevent a phenomenon that the power of the auxiliary power supply system is discharged, which may occur in cases which are not power outage situations due to CPU malfunction, caused by electromagnetic waves, , or malfunction due to a failure in the hardware configuration of the CPU or an error in software such as a control program.
